If everyone behaved as you did, then you would get either substantially worse service or substantially more expensive restaurants. Right now you're arbitraging the good will of other people to pay for the service that you're not willing to pay, i.e., freeloading; because you're still benefiting from the current system and not the experiencing other system you'd consider to be "fair".
